Development Squad coach Nick Haycock is determined to take his team's fine pre-season form into the campaign proper.

The Hammers U21s have gone unbeaten throughout the summer to date, and Tuesday's 2-0 win at Braintree Town represented a third clean sheet in four games.

Haycock is thrilled with the progress the team are making, but warned that the attitude and application must be maintained.

"I'm delighted with the way things are going," he said. "But obviously it will count for nothing if we don't take that form into the start of the season.

"There are two or three competitive games left in the pre-season - we have a tough game against Newport County at the weekend - but I'm delighted with the way the boys have applied themselves so far."

The Hammers have blooded several younger players in their friendly matches and Haycock has been impressed with their showings against senior opposition.

He continued: "Do we want to win leagues, do we want to win trophies? Yes it's important we put that into them, but it will never be at the expense of putting younger players in there when we know they can take that challenge.

"They'll make mistakes, but that is part of their learning, and I'm delighted with the young players out there. I wouldn't want to single anyone out because I thought everyone had a go.

"I think in the second half when the tempo went a little bit, we started to get more control and we started to see more of the type of the football we wanted to play.

"The first 20 minutes was difficult, Alan Devonshire has them well organised, they were at the top end of the Conference last year and very unlucky not to go up, and he runs that club on a shoestring budget compared to most others in that league.

"Being a West Ham person we're delighted to give him a game and it's always a pleasure to come over here and play against his teams because they're competitive workouts."

Whilst not wanting to single individuals out, striker Elliot Lee continues to catch the eye, and his double at Braintree took his pre-season tally to six. Haycock's challenge to the youngster is to keep his form going.

He added: "We keep saying what they have to do is keep knocking on the manager's door, and all they can do is put performances in.

"Elliot is a pleasure to work with on the training field, I've given him the captaincy over the pre-season with Dan Potts and Leo Chambers away with the first team.

"Every age level he's played at he's scored goals, and his attitude to want to get better and his drive is there for all to see. His second goal in particular was fantastic."
